I made a material which allows me to blend between 2 textures based off the vertex color to allow my mapper more flexibility in how surfaces look. The problem is that the vertex color is very blurry unless the mesh is very dense
So I used a ceil expression to make it more pronounced. While the effect is much stronger, it also looks very artificial.
Would there be a way to add noise or otherwise smooth out the mask edge to make it look less sharp?
Edit: Forgot to mention, this is the part of material that controls the vertex mask:
